I just noticed this now, but did the post box always have a built in spell checker? It underlines any words I spell incorrectly. I just noticed it now. Not sure if it's new or my spelling is just too good. :rolleyes:
Might be your OS or browser. Mac OS X has a built-in spelling checker. Altough in swedish for the moment >.<
Ok I think I know why now. I just upgraded to firefox 2.0 so that might be why.
